Q FUSE-SETTING MACHINE. 5

- Application mea January 24, 1928.;` sel-inne. 249,169.

The invention described herein, patentb ed, may be manufactured and. used by or `for the Government' for governmental purposesVv Without. the payment to me of any royalty` thereon.

The subject of this inventionis a fuse set;

The object of this invention is to provide means for preventing the vprematurevvith` dravval of the round from. the fuse-setting machine.l 1 With the foregoing-and? 'other-ohjec ts',in

view, my. invention residesy in thenovel `arf rangement and combination; otvpartsand in the details ofr construction hereinafterde-.e

A practical embodiment 'of 'theinvention is illustrated in the accompanying drawings,

wherein:

Disi posed axially Within the adjustingmember 7 is a spring pressed plunger 16 splined'to saidmember by means of a latch 17 Whichis pivoted inthe member andarranged lto engage behind the cap k18 of the round, when the i;l .L round, on being fully'inserted'has forced the plunger to the position shown in Fig. 2. The round is thus iseeurely'locked to the fuse set,`

In order to prevent actuation of the crank,

14 until such time as a round is inserted there is mounted in the housing 6 a 'spring pressed bolt 19 Which is normally engaged ina slot 2O in the adj usting memb'er 7; The bolt vis disengaged from the member 7 upon insertion of a round by means of a cam arm 21 disposed in the slot 2O and formed on a ring 22 Which Y is mounted on the-plunger 16 and connectedV thereto by a torsion spring 23. The cam arm 21 completes the connection between the ring and the adjusting member so that they Will be-rotated together but the slot 20 of suiiicient Width to permit a slight relative movement as indicated inuFig. 3 at Vtheterminati'on of the final revolutionv of the adjusting member. This relative movement is of a positive characterbeing effected by the `bolt 1.9 Whichispermitted to enter a groove 24 in the adjusting member during the termination of the second revolution of the adj usting r` 26 which strikes the'intermediate surface 27 oi' the latch andholds the latch' disengaged duringthe initial restoration of the plunger: 16 when the round isuremovedv` lVhen v-the` plunger has moved suilicientlyto cause the cam arm 21 to clear thebolt19 andpermit,

the torsion sprinor 23 to'realine'it with the bolt. the head 28 of the plunger Will have passed over the free end of the latch and Will serve j to hold itinV the disengaged position.

I claim:
